Parents of children at private WA schools should brace for fee rises up to four times the inflation rate next year, with new figures showing education costs leapt 37.5 per cent in the past five years.

Elite colleges said it was too early to set next year’s fees but they predicted rises between 5 and 8 per cent.

Principals said big pay rises to State schoolteachers last year in a three-year agreement were driving up fees at private schools because they competed for staff.

Scotch College principal Andrew Syme said fees at private schools had to go up at least 6 per cent to keep pace with teachers’ pay rises before any improvements in service.

Anglican Schools Commission chief executive Peter Laurence said fee rises at low-fee church schools would be similar to last year’s increases of between 6 and 9 per cent.

“Teachers’ pay is the number one driver that’s going to keep increases higher than they used to be a few years ago,” he said.

Australian Bureau of Statistics figures show education costs in Perth, comprising school fees and other miscellaneous costs, have jumped 37.5 per cent since 2004 – the biggest increase registered by any capital city. Canberra had the second biggest leap, with 29.4 per cent.

The rise was driven by a 55.9 per cent lift in fees associated with pre-schools and primary schools. By contrast, pre-school and primary school education costs in Sydney rose almost 23 per cent.

Pre-school and primary school fees have grown faster than the average wage of West Australians which, between 2004 and today, jumped 44 per cent – the biggest rise of any capital city.

The State Government has held down public primary school fees so the increase is mainly for private schools.

A private education in WA costs between $3000 a year for Year 12 tuition at low-fee Catholic schools and $17,000 a year at high-fee independent schools. Many private schools in Sydney and Melbourne charge more than $20,000 a year.

Association of Independent Schools of WA executive director Valerie Gould said the recent teacher pay rises and rising construction costs in the building boom two years ago may have been the big contributors to increased education costs.

WA Chamber of Commerce and Industry chief economist John Nicolaou said the fact fees were going up so much in the private sector reflected poorly on the public school sector.

He said people were voting with their feet and going to the private sector even while fees were rising, which said something about what parents thought of Government schools.

WA Secondary School Executives Association president Rob Nairn said students in Years 8 to 10 could get an education at a State school for a voluntary contribution of $235 a year. Costs were higher in Years 11 and 12 but much less than in private schools.
